For the past three months I have been tracking a problem and can't seem to find any consistencies, weather/temp, etc. The car seems to run fine, accelerate okay, but when I stop sometimes it acts like it is going to die but doesn't and then takes off. Finally, just made and apt for service next week. Since I am a woman, not much knowledge of cars, let alone a complicated car like my 05 roadster, can I get a few suggestions to sound more creditable when I go in with it? Please!

Is this the correct forum to post this one? I am new to all of this!! But love this car!!!
